Re: Debugging mysql limits
Just inheritance from an old design that has passed it's limits. I actually have a development version which does just that, but there is a lot of work to convert many php scripts and sql to include the new column. It's some way away from live though, so the problem I outlined still exists.

Re: Debugging mysql limits
Just a little more info on this. I tried setting all of this up on a home server with, as far as I can see, more or less identical specs with the exception being that it's a 64bit linux build rather than 32bit. Same insert on duplicate update takes 3 mins. I spent all day yesterday trying to figure out what limits are being hit without success. Would certainly appreciate any pointers to look at..

Re: mysql limits
Search speeds and CPU with MyISAM is quite good. I tried InnoDb and insert speeds was far too slow because of its row locking versus MyISAM's table locking. Some people have been able to fine tune InnoDb but it requires even more RAM because InnoDb works best when the entire table fits into memory. thanks...

thanks... my question was more like IF mysql can handle that amount of records - about 100 million... and if it's just a question of cpu power and memory? Hi, The limit for the table can be set when you create the table itself. the MAX_ROWS and AVG_ROW_LENGTH variables (m X n matrix) will decide the table size. MAX_ROWS limts the maximum number of rows in that table. The AVG_ROW_LENGTH variable decides the length of the row. The specified value can be used by a single column itself or depends on the size of the columns.

On one of my servers we currently have 1498 threads running, we are averaging 2044.431 queries per second, and 1 slow query for the past month. I restarted mysql on the wrong box on accident. But I would still consider these numbers to be nothing compared to some others around here. From time to time (2 weeks uptime or so), we have to face a Signal 11 crash (which is pretty scary, since we have to run a myisamchk that takes us offline for at least 1 hour). We believe this signal 11 is related to the MySQL server load (since we have changed OS's and hardware -- RAM mostly). What does it say in the mysql_error_log when this happens? Mysql will usually dump the reason out in the error log and it's pretty easy to solve after that. Have you considered using the binary version of MySQL instead of compiling from source? Our server is one P4 3GHz, 2GB RAM (400mhz), SCSI Ultra160 36GB disks (database only) running on OpenBSD 3.5.

We have already tried to increase key_buffer (along with the other settings), but it does not seem to hurt or to improve our performance (although, the memory use increases). 384 for key_buffer is probably fine with 2gigs of memory. Some will say that you can go up to 1/2 of the memory, but I like to stay around 400 myself. But it really varies based on what you are doing. We had to do a lot of testing of our application to find the right number. To track down this signal 11, we have just compiled MySQL with debugandreturned totheoriginal my-huge.cnf recommendations. Now it seems we are running on a overclocked 486 66mhz. That's what debug does. Use the binary, that's my recommendation. Is there any way to prevent this signal 11 to happen or is it a message that we have exceeded MySQL capability? Exceeded MySQL's capability? I don't think you have scratched the surface yet. Error messages are just that, an error of some type. Without knowing the version of MySQL you are running, it's even harder to know. Is MySQL able to handle such load with no problems/turbulences at all? If so, what would be the best hardware/OS configuration?
